Cell Block
The blood-brain barrier is "made" by this type of glial cell
Astrocytes
These types of potentials are "all or nothing."
Action potentials
Personality, time management, and planning are all functions carried out by this lobe.
Frontal lobe
The term "nerve fiber" refers to this specific part of a neuron.
Axon
How many pairs of cranial nerves are there?
12
These glial cells are affected by multiple sclerosis (MS)
Oligodendrocytes
The resting membrane potential of a neuron is _________.
-70 mV
This structure is the sensory relay station of the brain. It sends sensory info exactly where it needs to go.
Thalamus
Gray matter consists of a large concentration of this specific cell part.
Cell bodies (somas)
This nerve innervates most of the eye muscles, including the one that constricts the pupils.
Oculomotor (III)
Action potentials are generated (start) at this specific part of the neuron.
Axon hillock
These types of potentials are graded, can summate, and are not large enough to reach threshold.
Local potential
The ________ is responsible for all of your big emotions.
Limbic system
The _________ system carries involuntary motor commands to the muscles of your digestive tract, respiratory tract, and blood vessels.
Autonomic
This nerve carries sensory information from the face.
Trigeminal (V)
A group of cell bodies in the PNS is called ________.
Ganglion
When the membrane potentials reaches threshold, these types of channels open.
Voltage-gated sodium channels
The primary motor cortex can be found in this specific location of the brain.
Precentral gyrus
Afferent information is carried ____________ (toward or away from) the central nervous system
Toward
The glossopharyngeal nerve carries this type of information (sensory/motor/both)
Both
Ependymal cells make ________.
Cerebrospinal fluid (CSF)
This specific type of local potential will make it LESS likely for an action potential to occur.
IPSP
This area is responsible for understanding spoken language.
Wernicke's area
The cranial nerves are part of this division of the nervous system.
Peripheral
How could you test the function of the accessory nerve?
Turn head (SCM), shrug shoulders (trapezius)
